Title: Vacuum arc descaling device
Inventor: KONDO JIRO
IPC: B08B7/00
Filed: 1994-03-01
Abstract: PURPOSE:To improve the surface roughness by providing anodes connected to a positive pole of a power supply for vacuum arc and cathodes consisting of a material to be treated in a vacuum chamber, attaching a noncontact sealing mechanism on the inlet side of the vacuum chamber and providing a mechanism for controlling thickness of the liquid which is applied on the surface of the material to be treated in the vacuum chamber. CONSTITUTION:Since a sealing mechanism 14 without contact with the material 13 to be treated is provided on the inlet side of the vacuum chamber 10 of a vacuum arc descaling device, the sealing effect of the vacuum chamber is attained without providing differential pressure sealing chambers on the inlet and outlet sides of the vacuum chamber. The liquid 12 and/or a viscous material are applied on the surface of the material 13 to be treated, so the liquid 12 in the vicinity of an arc spot is turned into vapor, an arc is moved toward the vapor and the moving speed of the arc spot is increased. That is, arc discharge in a vacuum generates arc columns more than the discharge in the air, the arc columns are turned into cathode spots (arc spots) on the surface of the material 13 to be treated and get about in search of scale. When the moving speed is increased, the arc spots can not locally stay on the cathode and local excess melting is eliminated.

Title: Air preheater
Inventor: SATO SUSUMU
IPC: F22B31/08
Filed: 1987-02-16
Abstract: PURPOSE:To secure the inlet temperature of a coal pulverizer needed for drying and pulverizing in accordance with properties of coal to be used by making a rotary unit of an air preheater to be rotatable in both directions. CONSTITUTION:Provisions are made of a power source which allows the rotation in both directions as well as a rotary unit 2 which, connected to said power source, is rotatable in both directions. When coal has much moisture content, the rotary unit 2 is rotated in the normal direction. In this instance, a heat transfer element at high metal temperature which has been rotated from an exhaust gas sector 19 is further rotated to primary air sector 17 to secondary air sector 18 to fully evaporate the moisture content from the coal and dry the same in a coal pulverizer 11. On the other hand, when the moisture content in the coal is not so much, the rotational direction of the rotary unit 2 is reversed. In this instance, the heat transfer element is rotated from the secondary air sector 18 to the primary air sector 17, and so, the exhaust gas temperature at the outlet of the air preheater 1 is reduced so as to reduce the exhaust gas loss, improving the thermal efficiency of boiler.

Abstract: PURPOSE:To control the difference of speed variation between rolls to an allowable value or smaller by comparing the difference between the speed variation of a reference roll and that of a following-up roll with an allowable speed variation difference value. CONSTITUTION:If speed variations of a reference roll 2 and a following-up roll 1 which are nipped are different from each other by disturbance or the like, output signals 11a and 12a of rotative speed detectors attached to these rolls are made different from each other, and the difference between the speed variation of the reference roll and that of the following-up roll which is obtained by the characteristic of a comparison operating circuit 13 is outputted as a speed variation difference 13a. This output value is compared with a set value 14a which is set by a setting circuit 14 and is allowed on the characteristic of a nip roll device. If the difference 13a is larger than the set value 14a, a deviation 15a is outputted from an output generating circuit 15 as the speed correcting signal of the following-up roll 1 to correct the speed of the following-up roll 1, and the difference 13a is reduced, thereby controlling always the difference to the allowable value or smaller.

Title: Optical disk and reproduction method for reference signal
Inventor: TAKEMURA YOSHIYA
IPC: G11B20/10
Filed: 1985-02-20
Abstract: PURPOSE:To reduce the effect of the crosstalk produced between address signals and to attain correctly the reproduction of address signals, by providing an optical recording layer on a groove forming a recording track and also modulating the depth of the groove with (n) types of frequencies to record a reference signal shown by an n-notation code signal. CONSTITUTION:A photodetector 10 converts the reflected light into electric signals and delivers them. A preamplifier 11 amplifies the output signal of the photodetector 10 and obtains a reproduction signal (p). A BPF 12 has a center frequency f0 of a pass band and detects the component of the frequency f0 from the signal (p). While a BPF 13 has a center frequency f1 of a pass band and detects the component of the frequency f1 from the signal (p). A comparator 14 compares the detection signal (q) of the BPF 12 with the detection signal (r) of the BPF 13 and decides whether the signal (p) is equal to '0' or '1' of a code signal for reproduction of an address signal (s). The comparison of the component intensity is carried out between both frequencies f0 and f1 contained in the signal (p) and therefore it is satisfactory if a difference exists between the ratios of contents of those two frequency components. Thus the amplitude of modulation can be reduced for the depth of the groove and the crosstalk is reduced between adjacent grooves.

Title: Circuit switching system
Inventor: SANAGI ATSUTAKE
IPC: H04B1/74
Filed: 1980-03-13
Abstract: PURPOSE:To prevent the disorder caused by transmission of a wrong signal, by operating a receiving-end change-over switch of the circuit, only when the circuit number of the sending-end parallel switch has coincided with the circuit number of the sending-end parallel instruction. CONSTITUTION:In case when an sending-end parallel instruction has been transmitted to the sending-end side by mistake due to some reason, the fault is detected and the sending-end parallel switches 3, 3' are operated. After that, the sending-end transmits the circuit number which is equal to that which has been received through the control circuit 5, and the receiving-end switching instruction, to the receiving- end side by use of the control circuit 6. When it has been received, the receiving-end side operates the receiving-end change-over switch only when the circuit number of the sending-end parallel instruction which has been out to the sending-end has coincided with the circuit number which has been received. According to such a constitution, even if the sending-end parallel instruction is transmitted by mistake and a wrong sending-end parallel switch is operated, a wrong signal is not transmitted since the receiving-end change-over switch is not operated.

Title: Fuel cell power generation system
Inventor: IWASHITA SAKAE
IPC: H01M8/00
Filed: 1992-02-19
Abstract: PURPOSE:To improve overall heat economy by regulating the opening degree of a steam regulation valve, which divides steam separated by a steam separator to the outside and the inside of the system, as the quantity of supply heat toward the outside of the system coincides with the required quantity of heat supply. CONSTITUTION:A steam separator 19 circulates cooling water through a fuel cell 12 and separates steam generated in the cooling process, which is partly used for the improvement of raw fuel, and the remaining steam is discharged out of a fuel cell plant 1 as waste heat value 24. The discharged steam is divided by a steam regulation value 27A to the outside and the inside of the system, and steam sent back to the inside of the system is used to drive a turbine 17. At this time, quantity of supply heat taken out to the outside of the system is measured by a calorimeter 26A and required quantity of heat supply is set by a heat quantity setting device 28A. An arithmetic unit for opening degree 30 finds the difference between the quantity of supply heat and the required quantity of heat supply, calculates the opening degree with which the difference becomes zero, and sends opening degree command signal to the valve 27A. In this way, waste heat can be utilized effectively by collecting the waste heat left after subtracting the required heat at the outside of the system, and taking into the inside of the system.
